I had a rather difficult situation where my PC got into virus problem. Though I recovered from it - I am facing a problem as detailed below. For e.g. earlier I used to type "mail.yahoo.com" and the address used to get completed and the page appears but now it doesn't appear and I am getting the a page like "C:\Documents and Settings\N4741\Desktop\#mail.yahoo.com" where N4741 is my userid (which has administrator right as well). But surprisingly my registry is having the entries like (DefaultPrefix and Prefixes under URL in the registry correctly set). Still its not working.
Hope somebody would be able to help me.
